Two suspects rearrested in the Aruba disappearance of Natalee Holloway will be released, FOX News' Greta Van Susteren has learned.

Court officials told Van Susteren that the detention of two Surinamese brothers, Staish and Deepak Kalpoe, held since last Wednesday would not be extended.

A judge last Friday had ordered their extended detention.

Investigators were focusing in part on cell phone calls and text messages between the suspects, prosecutor Dop Kruimel told The Associated Press.

"It's part of the investigation," she said, declining to give further details. "We do everything we can to see what happened."

Van Susteren reported that she broke the news of the release by phone to Holloway's mother, Beth, as she arrived Friday in Aruba, and that she was devasted.

Holloway, of Mountain Brook, Ala., was last seen leaving a bar with the Kalpoes and Joran van der Sloot on May 30, 2005, hours before she was scheduled to board a plane home with high school classmates celebrating their graduation on the Dutch Caribbean island. She was 18 at the time.

A search by hundreds of volunteers, soldiers, police and FBI agents, even Dutch air force planes, turned up no trace of her. Her father, Dave Holloway, told The Associated Press he plans to launch a new effort to find her remains off the island's coast, using private boats.
